Hi all, where i worked and most US departments, use what is called the "One -Up Rule". This is where police can respond on a force scale from mere physical presence all the way to deadly force determined on the force presented by the perp. We don't attack, we attempt to de-escalate situations. Many of the public just don't get that. So, for instance if you weild a blade in front of the police-your headed for the coroners shelf. Or it may go the other way if you can be talked down and subdued by "softer" means.Thats on you. If you raise your fists, he may raise a baton, or engage you with back-up officers with or without: OC spray, or stun etc. The police have to win. Thats their job.They are forced to make split-second decisions that may have long range consequences. The police dont fight, they stop the threat. The police dont kill, they stop the threat. They are there to assist. They are there to save your ass, not kiss it. Of course this will not make everyone happy to hear, but regardless, remains true. Take care, keep training.
